Manage DockerHub Triggers with Codefresh UI
It is possible to define and manage DockerHub pipeline triggers with Codefresh UI.
Create a new DockerHub Trigger
To add a new DockerHub trigger, navigate to Codefresh Pipeline Configuration view and expand Triggers section. Press the
Add Trigger button and select a
Registry trigger type to add.
Fill the following information:
- Registry Provider - select
- Namespace - put DockerHub user name or organization name here
- Name - DockerHub image repository name
- Action - select
- Filter - optional filter to specify which image tags will trigger pipeline execution: Re2 regular expression
Setup DockerHub Webhook
Currently Codefresh does not support to automatically setup a DockerHub webhook. You need to do this manually. Press
View Trigger button and see detailed instructions with URL links and secrets of how-to setup a DockerHub Webhook.
- visit DockerHub image settings page following link in help
- add a new DockerHub Webhook with previously copied
Triggering Codefresh pipeline with DockerHub push
Now, every time you push a new Docker image to selected DockerHub repository, manually, with Codefresh or any other CI/CD tool, Codefresh will trigger execution of all pipelines associated with this DockerHub Push trigger event.
Manage DockerHub Triggers with Codefresh CLI
It is possible to use
codefresh command line client (
CLI) to manage DockerHub pipeline triggers.
Docker Hub Trigger
It is possible to trigger a Codefresh CD pipeline(s) when a new Docker image pushed into DockerHub.
You can use Codefresh CLI to setup a Codefresh trigger for DockerHub.
Create DockerHub trigger-event
First, create a
trigger-event for every DockerHub image, you would like to setup a Codefresh trigger.
# create DockerHub trigger event for codefresh/fortune codefresh create trigger-event --type registry --kind dockerhub --value namespace=codefresh --value name=fortune # on success trigger-event UID will be printed out Trigger event: registry:dockerhub:codefresh:fortune:push:107e9db97062 was successfully created.
Setup DockerHub Webhook
Currently, an additional manual work is required to bind DockerHub
push image event to the Codefresh
# get trigger-event details for previously created trigger-event codefresh get trigger-event -o yaml registry:dockerhub:codefresh:fortune:push:107e9db97062
… command output:
uri: 'registry:dockerhub:codefresh:fortune:push:107e9db97062' type: registry kind: dockerhub public: false secret: aGao5weuez2G6WF9 status: active endpoint: >- https://g.codefresh.io/nomios/dockerhub?account=107e9db97062&secret=aGao5weuez2G6WF9 description: Docker Hub codefresh/fortune push event help: >- Docker Hub webhooks fire when an image is built in, pushed or a new tag is added to, your repository. Configure Docker Hub webhooks on https://hub.docker.com/r/codefresh/fortune/~/settings/webhooks/ Add following Codefresh Docker Hub webhook endpoint https://g.codefresh.io/nomios/dockerhub?account=107e9db97062&secret=aGao5weuez2G6WF9
- visit DockerHub settings page https://hub.docker.com/r/codefresh/fortune/~/settings/webhooks/
- add a new Webhook with previously copied
Setup pipeline trigger
Now, lets setup a new pipeline trigger, linking previously defined DockerHub push
trigger-event to one ore more Codefresh pipelines.
# create trigger, linking trigger-event UID to the pipeline UID codefresh create trigger "registry:dockerhub:codefresh:fortune:push:107e9db97062" 7a5622e4b1ad5ba0018a3c9c # create another trigger, linking the same trigger-event to another pipeline codefresh create trigger "registry:dockerhub:codefresh:fortune:push:107e9db97062" 4a5634e4b2cd6baf021a3c0a
From now on, Codefresh will trigger pipeline execution when new
codefresh/fortune image is pushed to the DockerHub.
DockerHub Event payload
The following variables will be available for any Codefresh pipeline linked to a DockerHub
EVENT_NAMESPACE- DockerHub namespace (alias
EVENT_NAME- DockerHub image name (alias
EVENT_TAG- Docker image tag
EVENT_PUSHER- user who pushed this Docker image
EVENT_PUSHED_AT- timestamp for push event
EVENT_PAYLOAD- original DockerHub Webhook JSON payload
